The geological disasters caused by the ground deformation of goaf have brought huge security risks to ecological environment and society. Therefore, it is imminent realize effective monitoring stability analysis goaf. In this paper, taking gypsum mine in Diaodao District, Jingmen City as an example, through investigation overall structure distribution characteristics goaf, combined with mechani...

The development of fractures and conduits in karst aquifers the strength their water richness are key factors determining whether a intrusion will occur mine. In phosphorus mining process, if water-rich areas is carried out, sudden disasters can easily occur. Therefore, water-richness zoning aquifer on roof phosphate mine very important to protect against incidence This paper proposes random-fo...

sarcheshmeh copper mine, with the final reserves of 828 million tons of sulfur ore and average grade of 0.74%, is known to be the largest open pit of iran and most probably the second largest copper mine in the world. this mine is located in the seismotectonic zone of central-iran, and 23 km away from the 150 km long rafsanjan active fault.in this study the vulnerability of the west wall of the...

This paper aims at reducing greenhouse gas emissions, which contributes to carbon neutrality, and, the same time, preventing mine heat disasters and extracting highly mineralized (HM) water, so as realize synergy between CO2 storage (CS) geothermal extraction utilization (GEU) in a high temperature (HT) goaf. With this purpose, an innovative CS-GEU technology for HT HM water deep is proposed, b...

To understand the stability of coal and rock in areas normal faults disturbed by dynamic loads blasting, damage characteristics within a fault are investigated using similarity simulation tests. The mechanism for gas outbursts is analyzed theoretically, results indicate that maximum tensile stress vertical direction blasting hole normal-fault model 1.17 times no-fault model. propagation cracks ...

What is the relationship between politics and disasters and how does this relate to the recent boom in disaster studies? The introduction to this volume argues that the recent interest in disasters is not because there are more disasters, but because of two recent developments within the social sciences: first, a focus on rupture rather than on continuity and second, a focus on materiality. Dis...

Abstract With the increasing depth and intensity of coal mining, impact on ground pressure has become one main disasters facing seriously threatening mine safety. Introducing concept toughness urban design, building a joint prevention control system based active prediction analysis risk at back mining face according to geological deposit conditions technology passive warning using monitoring da...

Abstract As one of the most common disasters in deep mine roadway, floor heave has caused serious obstacles to transportation and normal production activities. The third section winch roadway mining area Qitaihe Longhu coal a due large buried depths semicoal rock maximum is 750 mm. For problem stability, this paper establishes mechanical model analyze stability by analogy with basement foundati...
